Generally, monofiber connector includes accurate cylindricality lasso, for making fiber end face aligned with each other and contacting.Optical fiber quilt It is fixed in the centre bore of lasso, to cause the light core of optical fiber to be located at the center on lasso axle.Then optical fiber connector is polished To allow the physical contact of fiber cores.Then, it can be used alignment sleeve that two such a lassos are aligned with each other, wherein be polished Optical fiber connector is pressed to realize the physical contact optics connection from an optical fiber to another optical fiber relative to each other.Physics connects Tactile optical connector is widely used.

Multiple fiber optical connector is usually using multi fiber lasso（Such as MT lassos）To provide from source optical fiber to reception optical fiber It is optical coupled.MT lassos guide optical fiber in molding hole array, and optical fiber is typically bonded to the molding hole array.Each lasso With two other hole, wherein guide finger is positioned in the hole so that lasso is aligned with each other and therefore make optical fiber be coupled Alignment.

Various other methods have also been used to realize that fiber-to-fiber is connected.Including：V-depression is to Barebone, for example It is present in Volition^TMIn photo-fibre and light cable jointer, and the bare fibre alignment in right boring hole array.Some Anknupfungskeregrifves（Example Such as, described in U.S. Patent No. 4,078, No. 852, the 4th, 421, No. 383 and the 7th, 033, No. 084）The profit in optical fiber connection With lens and/or reflecting surface.Each in these Anknupfungskeregrifves describes single goal connection system, such as straight line Connector or rigging-angle connector.

Fibre ribbon can be terminated in the case where separating optical fiber it is advantageous to provide one kind and also makes beam diameter big In the extended pattern light beam connector of fiber-to-fiber pitch.
